6 Claims.

This invention in general relates to machines for casting metal used inthe making of stereotype printing plates, and more particularly toimproved simplified means for adapting a pump of the kind indicated, todeliver molten metal selectively from any one of a plurality of nozzlesfor appropriate use according to the type, size and shape of the mold ininstant use.

Another object is to provide a novel multiple nozzle assembly adapted tobe operatively applied to conventional stereotype casting pumps forpermitting such a pump to be conveniently used for the casting ofstereotype printing plates of the most diverse sizes and shapes.

A further object is the provision of a novel attachment for the spout ofa metal casting pump adapting the said pump for use selectively withdifferent sizes and shapes of molds.

Other objects and advantages in the design, construction, arrangementand adaptation of parts will appear more fully in the detailshereinafter described and will be best understood when taking inconnection with the accompanying drawing in which:

Figure 1 is a fragmentary elevational view of a casting machine to whichan embodiment of my invention has been operatively applied;

Figure 2 is an enlarged elevational view, partly in section, with partsbroken away, of a multiple nozzle assembly embodying my invention,detached from the spout of the conventional metal casting machine shownin Figure 1; and

Figure 3 is a transverse sectionalview taken on line 33 of Figure 2,looking in the direction of the arrow.

While I have illustrated a preferred form of the invention, it will beunderstood the various instrumentalities of which my invention consistscan be variously arranged and organized and that my invention is notlimited to the precise arrangement and organization of theinstrumentalities as herein shown and described.

In the drawing, H designates a casting pump of conventional design andconstruction to which a nozzle assembly A embodying my invention hasbeen operatively applied. The casting pump includes the usual frame l2and a furnace housing l3 in which a melting pot i4 is arranged. Themelting pot as is provided with a pump cylinder i5 which is adapted todischarge molten metal into an outlet passage it connected thereto whenan operating handle ll is manipulated in the usual manner.

The above details form no part of the present invention being common tometal casting pumps in general, but will sufiice to show how my devicecan be conveniently applied to conventional apparatus of the kindindicated.

The nozzle assembly A embodying my invention hereinafter described maybe attached directly to 5, an extending portion Id of the spout 16 inany suitable manner or may include a pipe l 9 having a fiange 2i at oneend which is bolted or otherwise suitably secured to a flange 22 formedon the exteriorly projecting part l8 of the spout l6. At h). the otherend of the pipe l9, another flange 23 is provided on which latter ahollow nozzle-supporting' or spout member 24, forming a part of thenozzle assembly A, is detachably secured by the screw bolts 25. Themember 24, as best shown in 15 Figure 2, is formed with an annularprojecting portion or flange 2b, which is received in an annu lar grooveor pocket 21, provided by an annular member 28, having an inwardlydirected lip or fiange 29, and by a coacting rear surface or annu- .0lar portion 3|, of a nozzle-bearing member 32 forming a part of myassembly A. The nozzlebearing member 32 is formed with a shoulderedsurface as at 39 which contacts with an inner surface formed on themember 24, the member 25 32 being secured to the latter and the member28 in any suitable manner, as by the bolts 33, and is rotatably mountedon the inner or bearing surface 23 of the said member 2A, a considerablepart of the body portion of which is arranged within a 30 bore 3 formedin the member 32. The member 32 is formed with or has secured thereto aplurality of nozzles, in the present instance two, 35, 33 of diiferentsize and configuration, the bores 31, '38 respectively of which are ofdifferent capacity and shape and communicate with the bore.

By further inspection of Figure 2, it will be seen the bore of pipe [3communicates with an opening 89 provided in member 2A, the member 24being formed with an internal pocket 4i hav- 40 ing a shelving floor 42,and an outlet or spout 43. Adjacent the outlet 43, which communicateswith opening 39, the member 2 is formed with apair of depending lips 44,which are adapted to extend into the nozzle in immediate use, which inthe drawing is nozzle 36, and which serve as a guide for molten'metalwhen issuing from the outlet 43 into the nozzle being used, 'so' thatthe said molten'metal will not run into any interstices between themember 2 and the nozzlebearing member 32. The outlet 43 is formed byremoving or cutting out a portion of the walls, as at 46, of the pocket4!. Either of the nozzles 35, 36 may be brought into use or co-operationwith the outlet 43 by unscrewing the wing screw 41 which is threaded ina hole formed in the member 28 and engaged against the said annularflange 26, thereby permitting the annular member 28, which is fastenedto the nozzle bearing member 32, to be turned by a handle or element 48secured to a lug or extension 49 arranged on the body portion of member32 for the pur pose of turning the nozzles 35, 36 secured thereto. Whenthe nozzle selected is in correct depending position and alignment withoutlet 43, the wing screw 41 is tightened and the device is again readyfor operation.

It will now be obvious that when the operating handle I! is manipulated,molten metal will be raised in the outlet passage I6 and conveyed intothe pocket 4| through opening 39, thence passing through outlet 43between and out of the lips 44, 45, into the bore 38, of nozzle 36 ininstant use at a point below the level of the contacting surfaces of themembers 24 and 32, to be discharged thence into the customary molds,which may be done by means of the present invention through the nozzlebest adapted for the purpose, by rotating the nozzle-bearing member 32by handle 48 until the preferred nozzle is in the operative positionshown in Figures 1 and 2. In practice, it has been found desirable topour molten metal into stereotype molds from nozzles of differentconfigurations and sizes, so that the most efficient application ofmolten metal to the said molds may be made, it being understood that incertain instances, it is preferable to have a wide flattened type ofnozzle and again in other cases, a round nozzle may be an advantage. Byinspection of Figure 2, it will be observed that the extremities of thelips 44, 45 of the nozzle-supporting member 24 are positionedsubstantially below the level of the inner or bearing surface 20 of thesaid member 24 so that molten metal will be prevented from finding itsway into the joints or interstices between said nozzle assembly and thehollow nozzle supporting member. The entrance of molten metal into thebearing of the rotatable nozzle-supporting member, it is of courseunderstood, would result in binding it when themetal cools. ing anadjustable nozzle assembly having a pair of nozzles, but if desirableother additional nozzles may be provided as a part of the assembly A.

I am aware that the invention may be embodied in other specific formswithout departing from the spirit or essential attributes thereof, and Itherefore desire the present embodiment to be considered in all respectsas illustrative and not restrictive, reference being had to the appendedclaims rather than to the foregoing description to indicate the scope ofthe invention.
